Realtek Soundcare Constant Buzz

Yesterday, between my First Lich King kill, and going to play Gmod. My mic decided to start making a constant buzz noise. The mic still records sound, and works with Ventrilo skype, and windows recorder, but it makes a constant hum noise. The noise is as loud as my talking, If I make my mic louder, the hum gets louder.

I've tried:
Pluging my mic into the back of my computer, and the same buzz noise as the front. (But the sound from my headset speakers was alot better)
Uninstalled my driver and rebooted and it auto installed. Same noise.
I tested my headset on my laptop, and it works fine.
I download the lastest Realtek drivers and installed them. Still same noise.
I've tried doing a 20 dB boost. Same noise, just louder.

My friends in vent/skype say they can hear me talking, just a loud buzz noise is covering my voice.

I've tried recording my sound also, and it sounds the same.

I dont know what else to do! All it leaves is my sound card being wonky, but if it was broken. Wouldnt my sound suck also? not just my recording?

Please help.

I can record a sample, if needed.

Edit:

I was just recording to see test it again, I noticed something wierd. When I move my hand closer to the mic, the buzz sound gets louder! I dont know why. Weird.
